Native library loading is back to the way it used to be with the addition of LWJGL 3.x libraries added with a different key.
Moved LWJGL 3.x repository definition to build.grade in that module. Fixed an issue where frame rate limit would cause GLFW frequency window hint to be set rather than use a software limiter. Removed LWJGLTimer for lwjgl3 module, no need for it any more, we'll just use the NanoTimer. Removed LWJGLCanvas for lwjgl3 module, can't implement this so we'll leave it for now.experimental
